Description

Technical Field

[0001] This utility model relates to the field of industrial equipment technology, and in particular to an environmentally friendly treatment device for synthesizing benzophenone. Background Technology

[0002] The synthesis of benzophenone produces gases containing harmful substances. Direct release of these gases into the atmosphere would cause severe environmental pollution, jeopardizing ecological balance and human health. While some gas treatment devices exist, their effectiveness in handling these gases is often inadequate. For example, some devices fail to absorb the gases sufficiently, resulting in some harmful gases being released untreated; others have poor structural design, with short gas flow paths and insufficient contact time with the absorbent, affecting absorption efficiency. Therefore, a specialized environmentally friendly treatment device for benzophenone synthesis gases is needed to improve treatment efficiency and ensure environmental and human safety. Utility Model Content

[0003] This invention provides an environmentally friendly treatment device for synthesizing benzophenone, which solves the problems in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An environmentally friendly treatment device for synthesizing benzophenone includes a primary absorption tower, a secondary absorption tower, and a tertiary absorption tower. The primary absorption tower, the secondary absorption tower, and the tertiary absorption tower are connected by connecting pipes. The primary absorption tower and the tertiary absorption tower are provided with air inlet pipes and air outlet pipes on their surfaces. The primary absorption tower, the secondary absorption tower, and the tertiary absorption tower are also provided with water inlet pipes at their tops.

[0006] The inner walls of the primary absorption tower, the secondary absorption tower, and the tertiary absorption tower are equipped with guide plates, and the surfaces of the guide plates are equipped with vertical pipes. The interior of the vertical pipes is equipped with mounting plates connected to the water inlet pipes, and a nozzle connected to the surface of the vertical pipes is installed on one side of the mounting plates.

[0007] The connecting pipe has symmetrically arranged grooves inside its vertical section, and a spring is installed at the bottom of the groove. The other end of the spring is connected to a slider that is slidably connected to the inside of the groove. A T-shaped rod is connected to one side of the slider, and a plunger is connected to one end of the T-shaped rod. A partition is provided inside the connecting pipe, and a through groove connected to the plunger is opened at the center of the surface of the partition.

[0008] As a further description of the above technical solution:

[0009] The top of the partition is connected to a stop for blocking the plunger, the diameter of which is the same as the inner diameter of the through groove.

[0010] As a further description of the above technical solution:

[0011] The guide plates are spirally distributed on the inner walls of the primary absorption tower, the secondary absorption tower, and the tertiary absorption tower.

[0012] As a further description of the above technical solution:

[0013] The bottom of the primary, secondary, and tertiary absorption towers is funnel-shaped, and plugs are provided at the bottom of the primary, secondary, and tertiary absorption towers.

[0014] As a further description of the above technical solution:

[0015] A safety valve is installed on the surface of the connecting pipe.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] In this invention, by setting up connecting pipes and internal structures such as baffles, channels, plungers, and springs, the plungers can be moved into the channels by the action of the springs in the initial state, sealing the interior of each absorption tower. This facilitates the contact between the sprayed water from the nozzles and the exhaust gas, reducing the hydrogen chloride content in the gas. At the same time, the inner wall of the absorption tower is provided with spirally distributed guide plates, which guide the gas to rise in a spiral shape. This flow pattern prolongs the residence time of the gas in the absorption tower, allowing the gas and sprayed water to mix and contact more fully, further improving the absorption efficiency and enhancing the gas treatment effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3An environmentally friendly treatment device for synthesizing benzophenone includes a primary absorption tower 1, a secondary absorption tower 2, and a tertiary absorption tower 3, which facilitates the treatment of gas by passing through multiple absorption towers in sequence through a multi-stage absorption method. This design increases the number and duration of contact between the gas and the absorbent, enabling more thorough absorption of harmful substances in the gas, significantly improving the gas treatment effect, and effectively reducing harmful gas emissions. The absorption towers are connected by connecting pipes 4 to facilitate the transport of exhaust gas. The surface of the primary absorption tower 1 is connected to an inlet pipe 5 for transporting exhaust gas, while the surface of the tertiary absorption tower 3 is equipped with an outlet pipe 6 to transport the absorbed exhaust gas to the phosgene purification tower and alkali neutralization container for further treatment. Each absorption tower has guide plates 8 arranged in a spiral pattern, with a vertical pipe 9 at the center of each guide plate 8. The spiral pattern of the guide plates 8 guides the gas upwards in a spiral, extending the residence time of the gas within the absorption tower and allowing for more thorough mixing and contact between the gas and the absorbent. Inside the vertical pipe 9 is an mounting plate 10 connected to the inlet pipe 7, with nozzles 11 on the surface of the mounting plate 10 connected to the surface of the vertical pipe 9. This facilitates the delivery of the spray liquid to the nozzles 11 through the inlet pipe 7. To ensure that the exhaust gas remains inside each absorption tower for a sufficient time, symmetrical grooves 12 can be provided on the inner wall of the vertical section of the connecting pipe 4. A compression spring 13 is installed inside the groove 12, and a slider 14 is connected to one side of the compression spring 13. The slider 14 is connected to a T-shaped rod 15, and a plunger 16 is connected to the T-shaped rod 15. A baffle 17 is installed inside the connecting pipe 4, and the surface of the baffle 17 is provided to contact the plunger 16. The through groove 18 is designed to allow the slider 14 to move the T-shaped rod 15 and the plunger 16 via the force of the spring 13. This allows the plunger 16 to move into the through groove 18, enabling the exhaust gas to remain inside each absorption tower for a sufficient time. As the amount of exhaust gas increases, the pressure inside each absorption tower also increases, pushing the plunger 16 and other components to move. This allows the exhaust gas inside the primary absorption tower 1 to enter the secondary absorption tower 2 for further spraying, thereby reducing the hydrogen chloride content in the exhaust gas.

[0026] Furthermore, in order to prevent exhaust gas from leaking inside the connecting pipe 4, the diameter of the plunger 16 needs to be the same as the inner diameter of the through groove 18, so as to avoid a large gap between them, which would lead to exhaust gas leakage. At the same time, in order to prevent the plunger 16 from moving too far, a stop 19 needs to be set on the surface of the partition 17. The stop 19 is located at the top of the through groove 18 and can block the plunger 16.

[0027] Furthermore, in order to facilitate the discharge of the spray liquid, the bottom of each absorption tower needs to be funnel-shaped, and the bottom of the absorption tower also needs to be threaded or otherwise detachable with a plug 21. When it is necessary to discharge the spray liquid inside the absorption tower, the plug 21 can be removed, and the spray liquid can be discharged through the spirally distributed guide plate 8 and the funnel-shaped bottom of the absorption tower.

[0028] Furthermore, to prevent safety accidents, a safety valve 20 needs to be installed on the surface of the connecting pipe 4. When the pressure inside the device exceeds the set value, the safety valve 20 can automatically open to release the excess pressure, thereby preventing safety accidents caused by excessive pressure and ensuring the safe and stable operation of the device.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
